I need help with the step by step ways to do certain tests on SPSS.

1. how do I find the mean, standard deviation, minimum and maximum age of a first exposure in a given dataset?

2. how do you look up the mean age of a dataset that's provided, and how do you find out the p-value and then apply this to find out the mean age?

3. how do you perform an equal variances test?

4. how do yo test to see if there is an association between 2 different things?

5. if data is not normally distributed, what test would you use to test if there is a difference in the median age between 2 different exposures?
